Through an empirical approach of several conspiracy theories (Knight Templars, Jesuits, Illuminati, Free-masons or Jewish conspiracy), I have noticed they develop six main characteristics. First, the conspiratorial myth points out scapegoats in a non-aleatory way. They usually belong to ethnical or religious minorities. Secondly, those scapegoats try to acquire an overwhelming power in all fields. Thirdly, to achieve this goal, they corrupt the whole society, especially on mores and sexuality. Fourthly, to set up their domination the scapegoats use the art of simulation and dissimulation. They yield a cult of secrecy. Fifthly, the scapegoats are consistently portrayed through symbolic morphological types, frequently as animals. Finally, conspiratorial myths undergo a process of hybridization and creolization. They go through transformations, alterations and medleys. Every conspiracy theories mix up into one another.
